Abstract

Selon cette invention, un ensemble tambour à dépression pour imprimante comporte un tambour doté, d'une part, d'un réseau de passages (40) répartis le long de ce tambour et autour de lui pour permettre à l'air de circuler de l'extérieur vers l'intérieur du tambour en réponse à une pression de l'air réduite à l'intérieur du tambour; et, d'autre part, d'un réseau de clapets (52), chaque clapet pouvant passer d'une position fermée, dans laquelle le clapet rétrécit au moins l'un de ces passages, à une position ouverte, correspondant à une ouverture plus grande de ce passage ou de ces passages. Ce dispositif est tel que, lorsqu'une zone partielle du tambour est enveloppée d'une feuille de matériau, au moins certains de ces clapets correspondant aux passages adjacents aux côtés de cette zone sont ouverts et les clapets correspondant aux passages qui ne sont pas recouverts par ladite feuille ni adjacents aux côtés de cette zone sont fermés. La zone ouverte du tambour est proportionnée de sorte qu'elle est petite dans les zones où il n'y a pas de papier. Ainsi, la zone ouverte du tambour s'adapte à la forme et à la taille du papier ainsi qu'à l'emplacement de ce papier sur le tambour et ce, tout en minimisant le débit d'aspiration requis. Une imprimante duplex comporte deux de ces ensembles tambour à dépression dotés de leurs tambours parallèles. La pression de l'air à l'intérieur de ces tambours est réduite et les tambours sont contrarotatifs. Le matériau devant être imprimé est amené au premier tambour de manière que le matériau puisse être maintenu sur le premier tambour grâce à la dépression et entraîné en rotation avec ce dernier. Une première tête d'impression imprime sur un côté de ce matériau. Ce matériau est alors libéré du premier tambour et passe au second tambour de manière que ledit matériau puisse être maintenu sur ce second tambour et entraîné en rotation avec ce dernier. Une seconde tête d'impression imprime alors sur ce matériau situé sur ledit second tambour. La matériau est ensuite libéré de ce second tambour.
